(Cl. 144-496) This invention relates to tools or jigs for use by carpenters, millwrights, mechanics and the like, and in particular an adjustable stand particularly adapted for supporting a door in such a position that the upper edge is at a comfortable elevation to be worked on for cutting recesses for hinge plates and openings for locks and the like, and the stand is collapsible to facilitate transportation from one job to another or whereby the complete device may be carried in a tool bag or the like.

The purpose of this invention is to provide means for supporting a door, window sash, blind, or the like so that the upper edge is at a comfortable elevation and wherein the door or the like is rigidly held. I I

In cutting out parts of edges of doors, window sash, blinds, and the like to receive hinge plates, locks, sash cords, and the ilke the article is placed with one edge on the floor or on a bench and it is necessary for the carpenter to bend over or stand on a step, or the like to remove the material to form a hingle plate, lock, or sash cord opening and as it is necessary to locate such openings, particularly for hinge plates, in accurate positions, working with the edge of a door at a low elevation or in an elevated position requires considerable skill.

The object of this invention is, therefore, to provide means for supporting a door, window sash, blind, or the like whereby the upper edge is located at an elevation that corresponds with the height or size of the carpenter or mechanic using the device.

Another object of the invention is to provide a supporting stand for doors, window sash, blinds, and the like in which the parts are readily adjustable.

Another important object of the invention is to provide a supporting stand for holding a door, window sash, blind, or the like in which the parts are separable so that the stand may readily be carried from one position to another.

A further object of the invention is to provide a collapsi ble stand for supporting doors, window sash, blinds and the like in which such articles are rigidly held and in which the stand is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies an elongated beam having transversely disposed rails at the ends with knobs or resilient material'on lower ends of posts at the ends of the rails and also at points on the beam and with door positioning FIGURE 1 is a front elevational view of the improved door, window sash, and blind holding buck with parts of the shelf at the rear thereof broken away showing a hinge connection in the intermediate part thereof.
